Be it known that 1, JOHN 'J. SULLIVAN, of Brooklyn, New York, haveinvented certain new and useful Improvements in Box-Nailing Machines,set fort-11in thislspecification and the drawings thereof. i V Theinvention consists of improvements relating to the hopper and the stopsof the nailfeeder, and to themechanism by which the nail-feeder isoperated, and to the connection therewith of the stopping, starting,andnaildriving mechanism, whereby nails in bulk in thethopper will beplaced in the nail-boxes singly and driven into the work. [Figure .1 isaside View of the machine. Fig.2is a front View of the same. Fig. 3 is atop View of the lower portion thereof with theupper part removed. Figs.4, 5, and 8 are detail viewsfofportions of the machine. Fig. 6 is asectional yiew of the nail-feeder, and Fig. 7 jisa toplyiew of the same.

In the form of construction shown, on the frame A, Fig. 3, are fourbearings, B, in which are supported the journals 0 of the shafts D E. Onthe'shaft D is a .c lriyingu1ley',F, which is driven by abelt from.suitable drivingpower.

The driving-pulley F is loose 011 the shaft D,

and has a conicalrecess, G, into which is fitted a conicalfriction-pulley, H i The friction-pub ley H has a neck,K, with a flange,L, and is loose on the shaft D,"but is held from turning thereon bya'groove, M, and feather N. The friction-pulley His operated back andforth on the shaft D into and outof the conical recess G, to fastenorunfasten the pulleyF to or from the shaft D,by acollarf,O, on theneckK and an elbow-lever, 1?. The collar 0 is pivoted by bolts Qbetweenthe forks R of the short arm S of the elbow-lever P, whichlhas for itsfulcrum rockshaft, U, .supported in bearings V in the. frame A. Thelongarm W" of the elbow-l ever 1? has a foot-piece, X, and aretractingspring, Y. By applying pressure to the foot-piece X when thepulley Fis in motion, theirictiompulley H is forced into the conicalrecess G in the pulley F, and byjfrictionfis locked therein and causesthe shaft D to be driven. The pinion Z onthe end of shaft D drives thecog-wheel A on the end of shaft E, and gives motion thereto. On

shaft E is a pinion, B, and a cam-wheel, Of. The cam-wheel O has LG2L111,.D, on its side. On the shaft U is an arm, E, having at its upper end aroller, F, which rolls against the cam D on the cam-wheel O. The arm Eis adjustable by set-screw G. WVhen the pressare is suddenly applied tothefoot-piece X, the lever I depressed, the friction pulley H engagedwith the pulley F, and the shafts D E in motion, andthe pressuresuddenly removed from the foot-piece X, the roller F operates againstthe cam Don the side of the camwheel 0, and holds the frictionpulley Hengaged with the pulley F until one revolution of the cam-wheel G ismade, when the roller F drops into a notch, H, at the end of the.

cam D and releases the friction-pulley'H from the pulley F, which isthen drawn back by the retracting-springY against the friction brake Kon theframeA, and themotion of shaft=D isstopped. i T

The brake K is adj ustable by setscrews in the frame A, and may pressthe edge or back of the friction-pulley H. As the motion ofjshaft Disintermittent, dependin as it does, upon the operation of the elbow-leverP,the friction-pulley H, the roller F, and the mm D, sothe motion ofshaft E is also intermittent. On the end of shaft E isa crank, L, whichhas a wrist-connection, ll with pitinan N, Fig.

.1, to which it imparts intermittent motion.

Pitman N is connected by awrist, 0, Fig. 2, to the segments P andimparts intermittent motionto them. The segments 1? are fixed at theircenters to the ends of short shafts Q, having bearing S on the frame Aand cranks T at their other ends. To the wrists, N of cranks T are.connected short pitmen V, which are connected at their other ends bypivot-bolts V tothe cross-head X and impart intermittent motion to itfrom the segments. The partsK L have channels V, which formnail-groovesU into which enter nail-tubesX Fig. 1. The nails descend through thenail-tubes X and the nail-grooves U into the nail-guides T and ontot-heclosed end WV thereof, and rest on their points until the nail-punchesdescend, strike the nails on their heads, and force open the slides ordies 0 and drive the nails through the nail- 1 boxes E".

boxes Ff into the work to be nailed ,to form theboxes; The work isplaced on alt-able, Y Fig. 2, under the nail-.box'es E and against aback plate, Z. The table and the back 5 -plate, 56, are both adjustableto suit the work.

The table Y is adjustable by arms A, passing through slots B in the backplate, Z, and-eons. nected with a block, C, through which passes anadjusting-screw, I)", supported at its lower end in a socket, E, on theframers, and hav-= .Y, on the end of a short shaft, Ztsupported Iinbearings A on the frai-ne A. The shaft Z hasa crank, 13*, connected byawrist, C", to.

zo -pitman I), Fig. 1, to'which it imparts inter- Finittcnt motion. Thepitman D". has azcom- 1 =-1 iensating-joint, Ff, and is connected at itsup- 7 per end by slot and set-pivotF to a crank, G",

.-. on the end of an axis, H supported in bear- 2 5 ;ings I on the frameA.

On-the axis H? is supported by lugs and set so sews K, Figs. 7. and 8, ahopper, L, to which i nterm ittent motion isimparted by the pitman D i.Thehopper L has at its front insidejedge in- 0 'eli'ned chutes Mandbeonduits N,- leading to -1 them.

The chutes h are inclined forward, .and in front .of each chute MB, onthe frontof.

im-the hopper L areswinging guide-springs O. 1 '3 :The chutes M may beany number desired 1 5 to suit the work; Five 'is a very. convenient.

' number.- The swinging guide-springsclose the front of the. chutes M,and can be turned to one side to give access thereto? Whenlnails'areplacedi'nthehopper L 'in bulk, the

g inte'rmittent tilting motion of the hopper If forces the nails forwardinto the conduits h" and chute's M2, and back of the spring-guides intothe inclined channels P, formed by z the V-bars Q having inclined tracksR be- Z15 .tween them." 1 Thenails drop point foremost into the 1 tracksR are held therein by their "heads, and slide down the tracks in singlefile.

'--The'V-bars have extensions S without the V,

.and arefadjustable to vary the width of the trackto suitdifferent-sized nails by lugs. and

set-screws T The nails that doinotbeeome "suspended in the tracks andslide down therein drop through the spaces U A guard, V, is

L placed around the tracks to stopthe waste 5 .11ails from comingforward; but itis provided wtracks to pass through it.

.supported on cross-pieces X on the frame A. To a projection, Y", Figs.1 and 2, on the with openings V to permit the nails inthe The V-bars arecross-head X. is pivoted by a pivot-bolt, Z",

The cams F, Fig. 7, operate intermittently againsta bar, H,

The pinion B, 3, on shaftEv imparts intermittent motion toa cog-wheel,

supported in inclined slots 1, Fig. 6, in the frame A,-and move the barH 'backward in theslots I; The bar H is drawn forward again in the slots1 by the retractingsprings K, Fig. 1. The cams G and compressionspringsL operate the bar M in the slots N in a similar manner. .Throughopenings in the bars and M, Fig. 7 are connected in a self-adjustingmanner stops 0" P*, which pass through slots Q" in a supporting-bar, R,fastened to the frame A. The stops have compression-springs S" and nutsT, Fig. 6, to make them yielding and self-adjusting. The stops 0" in oneposition are held by the retracting-springs K, Fig. 1, and thecompressionsprings S, Fig. 6, against the ends of the tracks R", andprevent the discharge of nails therefrom into the nail-tubes X andthence into the nail-boxes 13' under theiiaiLpunehes Ai",butv when drawnback by the vcams.F per- 'mit the nails to so descend. When the. stops 0are drawn back, the stops 1? areforced forward 'andpermitbutone hailfrom each track B -to descend.

To the bar H ,,Fig. 7, is connecteda-rnis X, to which are adj u'stablyconnected by screws and nuts Y adjustable arms. Z, having end bearings Ainwhich is supported a roller, 0, working on guides D. As the bar Hmoves forward, the roller 0- presses against the nails in the tracks Rand susp'ends'the.movements of-the nails downward, but as the bar H isdrawn back the roller 0* is raised from the "nails'onto the guides D andpermits the, nails .toadvance. To the side of the hopper-1 iare pivotedarms E", which in a like manner, support and operate the roller F tocause thev nails'to be evenly distributed in the track-R". .Aplate, Thaving offsets U and slotsvV, is placed under the nuts T" of the middlestops 0", the outerstops 0 being. left free." The plate T is pivoted atV to thelever X, by which it is operated to force the offsets U. underthenuts T of the middle stops, 0", to render them inoperative oroperative, and there- .byto stop or start the nailsin thecorrespondingl'tracks, tovar'y the number of nails to be driven at once.

The operating and starting and stopping mechanism, as described, and thenail-feeding and nail-driving devices in their general fea tures, asspecified, are well known, and for them I make no claim, broadly.

The details of eonstruction'and operation may be varied within the scopeof. the improvements.
